The Tideflex CheckMate inline check valve is ideal for backflow prevention. In outfalls, storm water applications, CSO applications and SSO applications, the CheckMate’s custom-engineered design eliminates costly backflow from oceans, rivers and interceptors. A major advantage of the CheckMate is low head loss. The valve opens to near full pipe diameter, maximizing the flow capacity of the... more

Over 20 years of field operation, research, development and engineering enhancements have combined to make the Tideflex TF-1 check valve incredibly reliable. The bill is formed into a curve that returns to a closed position every time, achieving the tightest possible seal for backflow operations, particularly at low flow rates. The eccentric flat-bottom design allows installation where the invert... more
